Derailment has a positive impact on businesses

That means good news for some businesses in the area that are seeing more customers because of the crash.

JC's grocery store in Mesa has seen between a 20 to 30% increase in customers. Some are regulars, others are workers cleaning up the twisted metal train cars, and others are travelers.

"We had some people traveling from Italy they just came down to vacation and they happened to stop at Mesa which is kind of weird, and they ended up seeing it, thought it was cool, took pictures of it," explains store employee Patricia Alvarado.

Some residents we caught up with say they haven't had any issues except for coal dust outside of their home.

BNSF says they still don't know the cause of the accident, but say the twisted metal should be cleaned up in two weeks.
